Programs also offer advice on nutrition, recovery techniques, mental training strategies and race preparation. All athletes are expected to train with a heart-rate monitor and keep a daily training journal.

Lactate testing fees ($195 single sport and $375 Bike & Run) are NOT included in the coaching program fees below. Athletes who are not local to Gareth will be asked to find a lab local to them who can test them or to invest in a simple lactate analyzer for home testing.

Foreword by Ironman Hall of Fame inductee, Bob Babbitt


“Gareth first started coaching me back in 2004 when I was racing professionally as a Triathlete. Since 2008 when I transitioned to cycling professionally, Gareth has continued to be there supporting me with lab testing and consulting. He is simply one of the very best”.

Kathryn DonovanProfessional Cyclist & Ex-Pro Triathlete

“With Gareth I am able to quantify my running improvements not just from race to race, but also throughout my training cycle. In just two years I’ve improved my marathon time by 25 minutes and qualified for the Boston marathon. Gareth gives me the tools to know how to manage my race performance over any distance and led me to successfully completing races from 26.2 to 100 miles”.

Lucia McIntoshAge Group Marathon and Ultra Runner

“Gareth coached me for many seasons at the height of my professional Triathlon career. With his help I won Ironman Malaysia and had many top 5 places including at Ironman California, Ironman Austria and Ironman Florida. His approach is deeply scientific yet easy to apply to daily training”.

Jan StrangmullerProfessional Ironman Triathlon Champion

“I first met Coach Gareth in 2000 and immediately knew his Attention to detail & scientific approach was a winning choice. Now 16 years later with a growing family and limited training time the precision of Gareth’s training plans allow me to not waste anytime and still chase my dreams.”

Jamey Yanik2015 US National Masters TT Cycling Champion & Elite Xterra athlete
